Thank you very much for sharing your in-depth knowledge - Is there a special reason that you are using k8s 1.16 ? also when you ran kubectl get nodes - I do not see master node ! - is that a special cluster.

@RahulWagh 3 жыл бұрын

You are welcome. There is no special reason for using k8s 1.16, it’s just I had it setup already on my laptop for long time and did not upgrade it. Regarding the master node yeah it’s my local development cluster on which I do lots of POC and experiments but the core concepts on converting k8s to helm still remains the same. But thanks for mentioning I will upgrade my k8s. //Rahul

Thanks for amezing video. Do we need to open loadbalancer port 8080 in the firewall rule or its automatically getting added while accessing application from internet

@RahulWagh 3 жыл бұрын

Port 8080 does not get added automatically into the firewall, so incase if you are not able to access the application due the firewall blocking your port. Then please add port 8080 to firewall. //Rahul

Rahul thanks for posting the video. I have got 4 questions . 1) For image you have mentioned "rahulwagh17/kubernetes:jhooq-k8s-springboot" , from where is the image getting downloaded as I don't see URL. 2) Can I replace image with say for example Centos from Docker hub? 3) Whats the default image repository for HELM ? Can I put multiple image locations , does it require username/password for repository/Hub?

Good content, thanks! Suppose I've 30 java services for which we've respective yamls of deployments/services etc. How do you suggest to deploy all 30 services using helm chart? Different chart for each service? or anyway we can use single chart to deploy all services.

@RahulWagh 3 жыл бұрын

Thanks chetan! But let me ask you some questions on your 30 java services - 1. Does all the 30 services are packed inside one docker container ? 2. Do you have 30 different container for 30 java services? //Rahul

@iammrchetan 3 жыл бұрын

@@RahulWagh 30 java services = 30 yamls of k8s deployment & k8s services so any java service is running with 1 k8s deployment with x number of pods. Any pod contains 1 container in it. I hope I've made it clear.

@RahulWagh 3 жыл бұрын

I can think of one solution where you need to create your own values.yaml which will contain all the 30 entries of your java services. You can iterate values.yaml and then deploy inside kubernetes cluster using helm chart. here is the reference example - jhooq.com/helm-pass-environment-variables/#22-iterate-over-key-value-map //Rahul

sir what does the targetport:http means ?

@RahulWagh 9 ай бұрын

targetPort: This is the port on the pod that the Service or Ingress should forward traffic to. It’s where your application inside the pod is actually listening for traffic.

how to done multiple deployments with one helm chart ?

@RahulWagh 3 жыл бұрын

Well you need to play around values.yaml, first you need to create variable which will have list of deployment which you wanna perform for example - deploy-springboot-1, deploy-springboot-2, deploy-nodejs-3 etc.... Later you need to iterate over that variable inside your deployment.yaml and service.yaml. It just food for thought but this is the approach i would take. Let see if i can prepare some lab session around it in upcoming days
